Introducing Hue Job Browser
The Hue Job Browser application enables you to examine the Hadoop Map/Reduce jobs running on your Hadoop cluster. Job Browser presents the job and tasks in layers. The top layer is a list of jobs, and you can double-click a job to view a list of that job's tasks. You can then view a task's attempts and the properties of each attempt, such as state, start and end time, and output size. To troubleshoot failed jobs, you can also view the logs of each attempt. For more information about Hadoop Map/Reduce, see the Hadoop Map/Reduce Tutorial.
